Hey, I recently bought an 08 powerstroke..I have been looking at dpf/doc delete systems. I understand you have to have a programmer..as far as the exhaust sytem goes after the new delete system is it safe to still run the stock system..I know ford/navistar makes a huge deal about the exhaust tips being a key part of the dpf system and I did not know if it would effect anything after putting the delete system on. Also, I wanted to know what i could do after the dpf/doc delete..i cannot seem to find a full exhaust sytem that comes with that option..can i buy one of the dpf back sytems and bolt it to a dpf delete pipe???

I'm not completely sure what your question is, but you cannot delete the dpf alone and run the truck on stock tuning. Once you put an exhaust on and delete the dpf and all the sensors attached to it, you MUST have tuning on your truck to account for this.
As far as the tips go, on any truck with a dpf (all makes) the tips are designed to introduce ambient air to the exhaust gases before exiting out of the tip. This is because when the truck goes into regen the exhaust gas temps coming out of the tip are hot enough to burn you. The stock exhaust is designed to draw in outside air to cool these temps before exiting the tip, thats all. After deleting the dpf and proper tuning, there is no need for the factory tip.

yep,that is all i needed guys,thanks..yea I knew i had to get a tuner and I did find out i could bolt a dpf back system to the dpf delete pipe. But if i couldnt afford the aftermarket pipe i did not want the stock dpf back exhaust sytem to cause problems.

My Ford mech says you can gut the dpf and have no tuner and it will not go into constant regen. He has done it and has had no problems what so ever. i think i am going to do mine in a week or so i am sick of regens and had my engine replaced at 24,000 miles because of too many regens

I don't know about this as the sensors measure the pressure in the DPF to check to see if its full or not.

I would have him show you a truck with this done before you gut your 3,000 DPF. To me, the tuner is the better choice unless you have a spare DPF sitting around that you can afford to throw away.

I picked up a CAT/DPF from a wreck at the u-pull & Pay Boneyard for $ 100.00 (cash, I don't think they are supposed to sell emission control components) was alot less than a delete pipe, Im using a Spartan from my 08 Truck, just had to buy a new license (pricey) but less than a new tuner, If you are going to do this, pull the sensors for re-installation after, the DPF is easy if you have a large roto-hammer, the CAT is a pain in the a$$ but can be done. the system works good with or without the tuner, although after I got the Ford re-flash, there is a new code for low back-pressure, according to my Ford tech, so many DPFs are cracking and failing, this was added to sense that problem
